Ye Olde Heart Nebula
Here's the Heart Nebula (IC1805) in HaRGB. It's a work in progress -- need to spend some more time on the colour balance of this one (it was a tough blend, lots of gradients in the RGB from city light pollution).
FSQ-85 and STL-11000M
Exposure (minutes) H-alpha:R:G:B = 200:55:50:55
Captured on two nights in September 2010 from downtown Toronto, Canada
Thanks for looking!
